It won't be snow or sleet that may cause the spirit to plummet in the upcoming days, but a high-pressure system invading from Canada, National Weather Service officials said.

This will drive frigid, dry air into the region, where it is likely to remain for a while. That means for the remainder of this week, temperatures are expected to max out in the mid-20s, said National Weather Service meteorologist Brian Ciemnecki.

"It's going to be really cold," he said, adding that the icy weather is expected to last into the New Year.

Those planning to watch the ball drop live in Times Square can expect a Siberian send-off to 2017. Temperatures will be in the teens in New York City and much colder to the north and west, Ciemnecki said.

But that shouldn't deter revelers, Ciemnecki said.

"I've seen them stand in the rain and the snow," the meteorologist said. "New Yorkers know how to dress for the cold."

There is a chance of slight accumulations of snow overnight Friday into Saturday, Ciemnecki said. Otherwise, the remainder of the week is expected to be precipitation-free, forecasters said.

In the past two years, the weather around this time has been unseasonably warm. In 2015, temperatures on Dec. 26 neared the record high of 66 degrees, which was set in 1982. People were seen in light sweaters and jackets on a jaunt through Central Park.

Those who are craving warmth this year, Ciemnecki said, will have to go to Jacksonville to find weather in the 50s or Miami to get temperatures in the 80s.
